H in the Military Alphabet: Hotel
Code word, pronunciation, history, and how to use it when spelling out loud
In the military alphabet, the letter H is Hotel, pronounced hoh-TELL with the stress on the second syllable. Hotel is one of the most international words in the alphabet — nearly identical in English, French, and Spanish — which is exactly why it was chosen to spell H over the radio.
Why "Hotel"?
Hotel reached English from the French hôtel, itself descended from the Latin hospitale, the same root that gives us hospital and hospitality. When ICAO's postwar project screened candidate words, it favored terms a pilot from any member state would recognize on first hearing, and hotel comes close to being a universal word. It made the 1951 ICAO list and rode through the testing period unchanged into the alphabet NATO adopted in 1956.
H Across Spelling Alphabets
| Alphabet | Word for H |
|---|---|
| NATO/ICAO | Hotel |
| LAPD | Henry |
| Western Union | Henry |
| German (Classic) | Heinrich |
| German (DIN 5009:2022) | Hamburg |
| French | Henri |
| Spanish | Historia |
| Italian | Hotel |
| Able Baker (WWII, historical) | How |
| RAF 1924 (historical) | Harry |
The RAF of 1924 spelled H as Harry; the WWII Able Baker alphabet used How. H's code word changed with every generation of the alphabet — Harry, then How — until the ICAO overhaul of the 1950s settled the matter with Hotel.
Hotel in the Field
At sea, the letter and the word travel together: the International Code of Signals flag for H is the Hotel flag, and flown alone it means 'I have a pilot on board.' Military time zones use single letters too, so just as Zulu means UTC, Hotel designates the UTC+8 zone. Aircraft registrations put the word in daily circulation — a Swiss aircraft's callsign starts 'Hotel Bravo,' because Swiss civil registrations begin with HB.
"H as in Hotel" on the Phone
The booking is under Hartley — H as in Hotel, A as in Alpha, R as in Romeo, T as in Tango.

ONE TO REMEMBER
NATO also used its code words as reporting names for Soviet submarine classes: K-19, the ill-fated boat portrayed in the film K-19: The Widowmaker, was a Hotel-class ballistic-missile submarine.
